NVIDIA introduced the DGX Spark desktop solution for AI development and prototyping, delivering up to 1000 TOPS (FP4) of AI performance a few months ago. The company has now unveiled the Jetson AGX Thor Developer Kit, which looks similar at first, but it’s designed for edge AI and robotics with I/Os for cameras and sensors.
The Jetson AGX Thor Developer Kit is equipped with a Jetson T5000 system-on-module with 2070 TOPS (FP4) of AI performance and high-bandwidth 128GB LPDDR5x memory, which delivers over 7.5x higher AI compute than the NVIDIA Jetson AGX Orin, and 3.5x better energy efficiency. A lower-end Jetson T4000 SoM is also in the works with 1200 TFLOPS and 64GB LPDDR5x.
Jetson T5000 and T4000 system-on-modules
Let’s look at the key features of the Jetson T5000 and T4000 first, noting that any information about the T4000 is still preliminary.

The devkit can process high-speed sensor data in real-time with 4x 25GbE networking, a camera offload engine, and a Holoscan Sensor Bridge (HSB in the specs above). It is designed to work with humanoid robotics and physical AI applications using the NVIDIA Isaac platform, NVIDIA Metropolis for visual agentic AI, and NVIDIA Holoscan for sensor processing. You’ll find more details on the Software page on the NVIDIA developer website, although there’s limited information about the Thor modules and devkit at this stage.
The kit is available for pre-order at $3,499 and up from Seeed Studio, Arrow, and RS Online, with backorders only and expected availability on November 20, 2025, per RS Online. The kit will ship with an NVIDIA Jetson T5000 module with heat sink, reference carrier board, a 140W power supply, a WiFi 6E module, a 1TB NVMe SSD, and a Quick Start Guide.
